PPTX converter

PPTX is for editing decks; PDF is for sending them. Slide conversions are heavyweight office work, so they run on our server engine rather than in your browser, and uploaded files are deleted automatically within 24-48 hours.

What is PPTX?

PPTX is the PowerPoint format Microsoft introduced with Office 2007: a zip archive of XML slide definitions, media and layout parts. It is the lingua franca of slide decks, but opening one still requires PowerPoint, LibreOffice or a cloud office suite, and rendering differs between them. Converting a deck to PDF freezes the slides exactly as rendered, which is why so many decks are shared that way.
